Description

Power Blocking Signal Generator for Enabling Remotely Rebooting Data Processing Apparatus}

The present invention relates to a communication device, and more particularly, to a data communication device installed in a multi-unit house such as an apartment.

As communication backbone networks using various media have been expanded and subscriber networks and communication equipment technologies have been developed, data communications, which have been limited to business facilities in the past, have spread to homes. In particular, recently, network devices such as home switches, home gateways, and home servers are installed in households, and network devices and subscriber network technologies are interlocked to enable real-time multimedia services through high-speed Internet access in the home, and information communication in the home. Home informatization, which connects devices and digital home appliances via a network, enables remote control and management, has been widely implemented. The government has also promoted the universalization of home automation and intelligent housing by implementing a system that certifies a high-speed information and communication building of a certain level for a multi-family or business facility with more than a certain standard on-premises information and communication facilities.

1 shows an example of a general multi-unit house wiring system. In the illustrated example, a main distribution frame (MDF) 10 is connected to a telephone station via an optical cable and to the Internet via an optical cable, a coaxial cable, or an HFC network. The main distribution board 10 is connected to the Intermediate Distributing Frame (IDF) 12 via an optical cable and / or an unshielded twisted pay (UTP) cable, and the intermediate distribution board 12 is connected to each generation through one or more UTP cables. It is connected to the terminal box 14. The household terminal box 14 of each generation is provided with equipment (not shown) such as a home switch, a home gateway, and a home server for constructing a home network, and the network equipment is provided at a plurality of outlets 16a to 16c in the household. Connected via a UTP cable, it is possible to provide services for information communication devices and digital home appliances connected to each outlet. On the other hand, some of the generation terminal box may be directly connected to the main wiring board, on the other hand, a separate building wiring board may be provided between the main wiring board and the intermediate wiring board.

In case of abnormality in the network equipment installed in the household terminal box 14 such as home switch, home gateway or home server in such a home network, the user calls the management company contracted by the construction company or the management office to recover. Upon request, management will visit the household and attempt to recover. However, since the household terminal box 14 is obscured by a large household appliance such as a furniture or a refrigerator, it is often difficult for the management personnel to access the household terminal box 14, and a visit time must be scheduled due to the possibility of the family member going out. There is considerable inefficiency in the management personnel performing the after-sales service. On the other hand, the failure that the user requests for recovery is restored to the initial state by turning off the network equipment in the generation terminal box 14 and rebooting the equipment, except in exceptional cases due to equipment failure or failure. In most cases, it is uneconomical for management personnel to visit and recover the household.

The present invention is to solve the above problems, by supplying a power cut-off signal to suspend the power supply to the data processing circuit of the data processing device when a failure occurs in the data processing device provided in the generation of the apartment house It is a technical object of the present invention to provide a power cutoff signal supply device capable of restoring a data processing device to an initial state by rebooting.

In the following description and the accompanying drawings, the same reference numerals are used for the same or corresponding parts for convenience of explanation and understanding.

2 shows an embodiment of a communication system in a multi-unit house according to the present invention. In this embodiment, the generation terminal box 20 is provided with a home network device 30, such as a home switch, a home server, a home gateway, or other device that performs a similar function. The home network device 30 operates by receiving DC power through the adapter 32, and is connected to each outlet (not shown) in the household through each UTP cable to distribute signals to each outlet. In particular, according to the present embodiment, the home network device 30 has a built-in power cut-off circuit, so that the system can be rebooted in response to a cutoff control signal applied from the outside as described later.

On the other hand, the intermediate wiring board 60 may be installed in each floor unit or aisle unit of the apartment house, for example, the intermediate wiring board 60, the integrated control concentrator 70 and the work group switch (W / G Switch, 90) ) Is installed. In front of the integrated control concentrator 70, a plurality of RJ-45 jacks are arranged in pairs. When the workgroup switch 90 is a 24-port switch, for example, 24 pairs of RJ-45 jack pairs in front of the integrated control concentrator 70 are provided. In each RJ-45 jack pair, the upper jack 72a is connected to one port of the workgroup switch 90 via a UTP cable 88 with RF-45 connectors at both ends, and the lower jack 72b is connected to the UTP. The cable 50 is connected to the home network device 30 of the corresponding generation terminal box 20. In addition, the front of the integrated control concentrator 70 is provided with an external console connection port 74 for connecting to an external console (not shown). The integrated control concentrator 70 generates a cutoff control signal for rebooting the home network apparatus 30 according to the instruction of the external console, and connects the home network apparatus 30 to the home network apparatus 30 through a line pair in the UTP cable 50. send. The workgroup switch 90 is connected to a main wiring room (not shown), aggregates the UTP cables 50 per generation terminal box 20 connected through the integrated control concentrator 70, and switches LAN generation between generations. do.

In a preferred embodiment, the home network device 30 installed in the household is connected to the workgroup switch 90 or the PSTN equipment via the integrated control concentrator 70 via a UTP cable. In the following description, for the sake of understanding, the description will be made based on the case where the home network device 30 is connected to a workgroup switch, which is a representative data communication device. It should be noted that only UTP cable 50 for data communication is shown in FIG. Meanwhile, reference numeral 34 in FIG. 2 denotes an RJ-45 jack for accommodating an RF-45 connector of a UTP cable 50 for data communication for connecting to an uplink data port, that is, the integrated control concentrator 70.

3 shows the data cable connection form of the integrated control concentrator 70 and the home network device 30 in more detail.

Generally, in case of 100BaseT UTP cable, only two pairs of lines (line pairs 1-2 and 3-6) are used for data communication among the four pairs of lines, and the remaining two pairs of lines (line pairs 4-5, Line pairs 7-8) are not used. Therefore, according to the present invention, the power cutoff control signal for the home network device 30 is connected to any one of the pair of lines (line pairs 4-5 and line 7-8) which are not used for data communication. Used to send Further, in view of the fact that the 4-5 line pairs can be used for voice communication, the 7-8 line pairs are used to transmit the cutoff control signal in the preferred embodiment.

To this end, in the integrated control concentrator 70, terminals 1-6 of the upper RJ-45 jack 72a connected to the workgroup switch 90 through the UTP cable 88 is connected to the lower RJ-45 jack ( 72b), the remaining terminals 7-8 are terminated, and terminals 7-8 of the lower RJ-45 jack 72b are connected to the cutoff control signal generating circuit. Accordingly, only three pairs of the four pairs of line pairs in the UTP cable 50 connecting the integrated control concentrator 70 and the home network device 30 are actually used for information transmission. In the line pair, a cutoff control signal transmitted by the cutoff control signal generation circuit of the integrated control concentrator 70 to the home network device 30 is carried.

On the other hand, in the modified embodiment, the home network device 30 installed in the household is connected to the PSTN equipment of the intermediate switchboard 60 or the main distribution room via the integrated control concentrator 70 by the PSTN communication UTP cable. Can be. At this time, the cutoff control signal may be transmitted using a pair of lines of the UTP cable for PSTN communication. In the case of voice communication, all four pairs of lines may be used for voice communication, but since the frequency of use of the 7-8 line pair is the lowest, it is preferable to use the 7-8 line pair for transmission of cutoff control signals according to the present invention. Do. In addition, when the integrated control concentrator 70 and the home network device 30 are connected by one strand of UTP cable to perform voice communication and data communication, cutoff control is performed using the 7-8 line pairs having the lowest frequency of use. It is desirable to transmit a signal.

FIG. 4 shows an embodiment of the home network device 30 shown in FIG. 2 in detail. The home network device 30 includes a switching circuit 38 and a regulation / power off circuit 40.

The switching circuit 38 switches signals transmitted and received by generation equipment connected to outlets in the generation. In addition, the switching circuit 38 is connected to the integrated control concentrator 70 by the UTP cable 50 through the uplink data port 34, so that generation equipment can transmit and receive data via the Internet or a LAN in a building or a complex. It allows you to. As mentioned above, three pairs of four pairs of terminals of the uplink data port 34 to which the UTP cable 50 is connected (ie, terminals 1 to 6) or two pairs (ie 1,2,3, Terminal 6) is actually used for data transmission between the switching circuit 38 and the integrated control concentrator 70, and terminal pairs 7-8 are used for transmission of the cutoff control signal.

In the regulation / power cut-off circuit 40, the constant voltage regulator 42 receives and regulates DC power through the adapter 32 to supply the constant voltage DC power to the switching circuit 38. In particular, in the present embodiment, the constant voltage regulator 42 has an enable (EN) input terminal to supply the constant voltage DC power to the switching circuit 38 only when the enable signal is in the "high" state and to enable it. No power is applied when the signal is "low". The photocoupler 44 receives the cutoff control signal received through the 7-8 terminal pair of the uplink data port 34, changes the logic state of the enable signal according to the level of the cutoff control signal, and provides a constant voltage regulator ( 42 to perform an isolation function to block the flow of backflow or outflow to the integrated control concentrator 70 through the UTP cable 50. Here, it is preferable to use the bidirectional photocoupler 44 so that the bidirectional photo coupler 44 can operate regardless of the polarity of the cutoff control signal. Pull-up resistor 46 serves to pull the enable signal to a "high" state. That is, the pull-up resistor 46 pulls up the enable signal to the "high" state when the cutoff control signal changes from the "high" state to the normal state, "low" state. A fuse 36 disposed between the adapter 32 connection terminal and the constant voltage regulator 42 serves to protect the device from overcurrent.

5 is a waveform diagram for explaining the operation of the regulation / power cut circuit 40. In this embodiment, the input voltage Vin which the constant voltage regulator 42 accepts from the adapter 32 connection terminal has a value of any level, for example, 9V, in the range of 5 to 24V. In addition, the blocking control signal CONT received from the integrated control concentrator 70 through the 7-8 terminal pair of the uplink data port 34 is at a "low" level in a normal state. Assume that the change to the "high" level during? T).

When the cutoff control signal CONT is at the " low " level, the light emitting elements in the photocoupler 44 do not emit light and the phototransistor remains in the " off " state. Since Vin is supplied as the enable signal EN, the enable signal EN is at the "high" level, and the output voltage Vout of the constant voltage regulator 42 maintains a normal value, for example, 5V. When the cutoff control signal CONT changes to the "high" level, any one of the light emitting elements in the photocoupler 44 emits light, and thus the phototransistor is changed to the "on" state, and the phototransistor is turned on. The enable signal is pulled down to the "low" level, and the output voltage Vout of the constant voltage regulator 42 drops to 0V. When the cutoff control signal CONT changes to the "low" level again after the power-down time ?? T, the phototransistor in the photocoupler 44 returns to the "off" state again, and the pull-up resistor 46 The enable EN signal is pulled up to the "high" level, and the output voltage Vout of the constant voltage regulator 42 returns to the normal value.

Meanwhile, in the modified embodiment of FIG. 4, the power cutoff circuit may be implemented by a simple relay instead of the regulation / power cutoff circuit 40.

FIG. 6 specifically shows an embodiment of the integrated control concentrator 70 shown in FIGS. 2 and 3. In this embodiment, a plurality of RJ-45 jack pairs 72a and 72b are disposed in front of the integrated control concentrator 70 corresponding to the number of ports of the workgroup switch 90, and an external console (not shown). An external console connection port 74 is provided. In addition, the integrated control concentrator 70 includes a microprocessor 76 or a microcontroller, a decoder 78, and a plurality of control signal drivers each provided corresponding to each of the RJ-45 jack pairs 72a and 72b. 80a-80x). The microprocessor 76 receives and interprets commands from an external console through the console connection port 74, and outputs an address designating a generation, ie, a home network device 30, which requires a system reboot according to the interpreted result. . The decoder 78 decodes the address data received from the microprocessor 76, and provides a driving signal to the control signal drivers 80a ˜ 80x corresponding to the home network apparatus 30 requiring the system reboot. The control signal driver receiving the driving signal outputs a cutoff control signal CONT that is activated for a predetermined time (eg, 3 seconds) so that the home network apparatus 30 is turned off and then turned on again to reboot.

FIG. 7 specifically shows any one of the control signal drivers 80a to 80x shown in FIG. 6. Each control signal driver 80a to 80x includes a photocoupler 82 and an overcurrent protection circuit 84. The photocoupler 82 receives the drive signal VD from the decoder 78 and outputs a cutoff control signal CONT whose level varies in accordance with the drive signal VD. The overcurrent protection circuit 84 provides a photocoupler ( It protects the photocoupler 82 by preventing the overcurrent flows to 82.

When the driving signal VD, which is an active-low signal, is at the "high" level, the light emitting element in the photocoupler 82 does not emit light, and the phototransistor remains in the "off" state, and the cutoff control signal CONT Is at the "low" level. In this state, when the driving signal VD changes to the "low" level, the light emitting element in the photocoupler 82 emits light, and thus the phototransistor changes to the "on" state, and the blocking control is performed by the phototransistor. Signal CONT is pulled up to the "high" level. When the driving signal VD changes to the "high" level again after the power down time ?? T, the phototransistor in the photocoupler 82 returns to the "off" state again, and the pull-down resistor 86 As the discharge is made, the cutoff control signal CONT returns to the "low" level.

As such, the integrated control concentrator 70 is connected to the home network device 30 within a specific household through a line pair of the UTP cable 50 in response to a command from an external console applied through the console connection port 74. By supplying the cutoff control signal, the home network device 30 can be rebooted. The external console may be a terminal such as a PC or a PDA directly connected to the console connection port 74 of the integrated control concentrator 70. In addition, the external console may be a management office PC that is connected through the wiring system in the apartment. However, in a preferred embodiment, the external console is a server of a remote monitoring system that remotely monitors communication facilities in apartment buildings via a communication network.

8 shows an embodiment of a console port integrated aggregation network for integrated management of the integrated control aggregation apparatus 70 at a remote location. In this embodiment, the integrated control concentrator is installed in the intermediate wiring board provided in the floor unit or passage unit of the apartment house. In order to distinguish and show a plurality of integrated control concentrators, the reference numerals 70a and 70b are denoted for each integrated control concentrator. The integrated control concentrators 70a and 70b control interruption for rebooting the home network devices 30a and 30y while mediating communication between the workgroup switches 90a and 90b and the home network devices 30a and 30y. Provides a signal to home network devices 30a, 30y.

Meanwhile, the console concentration apparatus 100 is provided in the main distribution board of the apartment house. The console concentrator 100 concentrates the console cables connected to the console connection ports 74a and 74b of the integrated control concentrators 70a and 70b to intensively manage the integrated control concentrators 70a and 70b. For this purpose, the console connection ports 74a, 74b of the respective integrated control concentrators 70a, 70b are provided with a plurality of monitoring ports 102, which can be connected to each other by, for example, a UTP cable, and on one side there is a remote control. An uplink port 104 for connecting to the management server 110 is provided. In addition, the console concentrating device 100 may additionally be provided with an equipment console port 106 for externally testing or controlling itself. In a preferred embodiment, the communication between the console concentrator 100 and the integrated control concentrators 70a, 70b is by RS-485 serial communication. On the other hand, the console centralization apparatus 100 is connected to the remote management server 110 by TCP / IP. The remote management server 110 can directly control the console centralized apparatus 100 through the Internet.

The above system operates as follows.

When the user recognizes that there is a failure in the home network device 30 and requests a recovery from the remote management server 110 operator, the remote management server 110 operator passes through the console centralized device 100. 70) to suspend the power supply suspend. Meanwhile, the remote management server 110 recognizes a failure of the home network device 30 by a separate remote monitoring system or by a verification program involving a PING test or other network communication function test and suspends the power supply. You can also grant commands automatically.

9 shows the process of enabling / disabling the blocking control signal in the integrated control concentrator 70. When a command is input through the console connection port 74 (step 150), the microprocessor 76 of the integrated control concentrator 70 attempts to interpret the command. If the command interpretation is successful and the command is a power supply suspend command through power off for a predetermined time (step 152), the microprocessor 76 decodes an address that designates a home network device 30 requiring a system reboot. Output to 78. The decoder 78 decodes the address data received from the microprocessor 76 (step 154).

Then, the decoder 78 drives a timer for counting the time for enabling the cutoff control signal (step 156), and transmits to a control signal driver 80a corresponding to the home network device 30 requiring a system reboot. By providing the driving signal until the timer expires, the blocking control signal is enabled (step 158). When the cutoff control signal is enabled, the output voltage of the constant voltage regulator 42 drops to 0V as the photocoupler 44 is turned on and the enable (EN) signal is deactivated in the home network device 30 shown in FIG. 4. The switching circuit 38 is thus turned off.

Referring to FIG. 9 again, if a predetermined time e.g. 3 seconds has elapsed and the timer is terminated in step 160, the decoder 78 disables the driving signal driven by the control signal driver 80a to block the control. The signal is disabled (step 162). When the cutoff control signal is disabled, the output voltage of the constant voltage regulator 42 returns to a normal value as the photocoupler 44 is turned off and the enable (EN) signal is activated in the home network device 30 shown in FIG. 4. Returning, the switching circuit 38 is turned on and rebooted.

In the above description, a power cut-off circuit for selectively supplying power to the switching circuit of the home network device 30 in accordance with the cutoff control signal supplied from the integrated control concentrator 70 is provided inside the main body of the home network device 30. Although the embodiment has been described, in the modified embodiment, the power cut-off circuit may be installed in the adapter of the home network device to selectively block the DC power itself input to the home network device. 10 shows such an embodiment.

Also in the embodiment of FIG. 10, the integrated control concentrator 70 and the workgroup switch 90 are installed in the intermediate wiring board 60 of the apartment house. Since the configuration, function and connection of the integrated control concentrator 70 and the workgroup switch 90 are similar to those of the embodiment of FIG. 2, a detailed description thereof will be omitted. Meanwhile, the generation terminal box 20 is provided with a home network device 230, for example, a home switch, a home server, a home gateway, or other device that performs a similar function. The home network device 230 operates by receiving DC power through the adapter 232, and is connected to each outlet (not shown) in the household through each UTP cable to distribute signals to each outlet.

According to the present embodiment, the adapter 232 of the home network device 230 is provided with an RJ-45 jack 232. In addition, the adapter 232 includes a power cut-off circuit 234, and selectively supplies power to the main body of the home network device 230 in response to the cutoff control signal received from the integrated control concentrator 70. Through the system of the home network device 230 is to be rebooted.

The home network device 230 is connected to the integrated control concentrator 70 using the link coupler 260 and the Y branch cable 270.

The terminal pairs 7-8, which are passages of the blocking control signal, are connected to the power interrupting circuit 238 among the two terminals. The AC-DC converter 236 receives the AC power, converts it into DC, and supplies the AC power to the apparatus main body 230a via the power cut-off circuit 238. The power cutoff circuit 238 selectively supplies the power from the AC-DC converter 236 to the apparatus main body 230a in accordance with the level of the cutoff control signal.

In one embodiment, the power down circuit 238 may be implemented by a relay or other switch. However, in an embodiment in which this embodiment is modified, the power cut-off circuit 238 may be implemented in the form of the regulation / power cut-off circuit 40 of FIG. 4, in which case the power failure regulator ( 242 may be omitted.
